主题：consumer search, firm heterogeneity, and platform design
摘要：
we study the optimal design of a monopoly platform that interacts with heterogeneous firms and consumers who face uncertainty about product values and prices. consumers search randomly among firms recommended by the platform. the platform designs a menu of contracts tailored to different firm types and allocates consumer visits across these firms. we show that the optimal platform design creates a “superstar effect,” whereby high-type firms capture a disproportionately large market share, and improves consumer welfare relative to the no-design benchmark.
